"Three is innocent, but dangerously temperamental. She is popular with the soldiers, listless and lethargic, and apathetic towards Zero. She clings tenaciously to her interests, but isn't bothered by what she doesn't care for." – Famitsu

Nah, that's pretty ridiculous as the dragon was confirmed as a 'he' in previous material. Although, either a brother or mother might be possible.

Knowing this series, literally A-N-Y-T-H-I-N-G can happen. Caim could come back to life, have made love to Nier's long, long ago ancestor and they had a kid, and that kid became a woman who made love to Seere and there ya go. Poetry.

I actually loved that Drakengard 2 had an actual "happy" ending, every other ending between Drakengard and NieR is a mix of shit-awful to bittersweet at best.

Actually, according to the pre-release manga for this game, Caim is not only alive and well, but still a prince of his old country (or a lord of a new one), instead of a shit-wrecking hobo who's so pissed off that he could kill Death.

It was also heavily implied that he was Red Eyes during Nier's backstory.
